When you enter the forest or walk along the beach, you can discover many things for yourself – the sound of waves hitting the sand, the chirping of birds in the trees.

But there’s a lot we don’t hear, and new technologies are bringing researchers closer to broadcasting our natural world than ever before.

“Most of the communication that occurs in nature is inaudible to us,” says Karen Bakker, author of The Sounds of Life: How Digital Technologies Bring Us Closer to the Animal and Plant Worlds.

“It occurs either above the upper limit of our hearing range, which is called ultrasound, or below the lower limit of our hearing range, which is called infrasound,” Bakker said.

From elephants imitating vehicle sounds to military sensors using live bees, from populating coral reefs with acoustic signals to the timeless song of whales, Becker explores how advances in recording technology and AI image recognition have been unheard of before. The corners of our world reveal life.
